If you're at all serious about using XML on your Web site, you should consider using XSLT to format your RSS feeds and convert them to browser-compliant HTML. Fortunately, you don't have to jump through too many hoops to do this--CPAN already has a tool for you, a package appropriately named XML::RSS::Tools.

This package integrates an HTTP client, an RSS parser and an XSLT engine into a single object that will download your RSS file, parse it, and apply XSLT style rules to it, all in a single sweep.
